recruiter for fishery products in grain size adjustable

摘要

The present invention relates to a selection device for ichthyological products (5), characterized in that its selecting size is adjustable and in that it is constituted by two surfaces or series of cylinders (3, 4) or rods that have an identical and constant pitch, one series being staggered by half a pitch with respect to the other, forming as a whole a selecting grille. The said two surfaces are superimposed and vertically adjustable with respect to each other, thus determining the selecting distance between the cylinders or rods of one surface with respect to the other.
